Abstract

Un système et un procédé pour une analyse non destructive d’une structure. Une sonde acquiert un signal de référence temporel transitoire et au moins un signal d’essai. Le signal de référence et les signaux d’essai sont transformés au domaine fréquentiel. Le signal d’essai du domaine fréquentiel peut être normalisé à l’aide du signal de référence du domaine fréquentiel. Des paramètres d’intérêt sont évalués à chaque emplacement d’essai en établissant des valeurs de paramètres estimées de manière itérative, en générant un signal d’essai de domaine fréquentiel estimé à l’aide des valeurs de paramètres estimées et en établissant la convergence entre le signal d’essai de domaine fréquentiel estimé et le signal d’essai de domaine fréquentiel normalisé. Les valeurs de paramètres sont établies en tant que valeurs de paramètres estimées découlant en une convergence maximisée entre le signal estimé et le signal d’essai normalisé. Les valeurs de paramètres peuvent être utilisées pour visualiser et modéliser diverses caractéristiques de la structure.
